Abstract
Molecular Communication (MC) is a nano-biocompatible promising system that conveys information via chemical signals through fluid or gases mediums. However, the design of MC requires low complexity and efficient power detection schemes to identify received bits under noise distortion. In this paper, we propose a novel detection scheme for molecular communication via diffusion (MCvD). Our system model consists of a single transmitter (Tx), a single receiver (Rx), and a free-diffusion-based propagation environment. The Tx uses a binary ON-OFF keying modulation scheme to modulate information. Our detection methods have been able to achieve un-coded BER levels down to 10(-5) at signal-to-noise ratios where traditional threshold detection achieves worse than10(-2).
